Question

Two stones are thrown vertically upwards simultaneously with their initial velocities u1 and u2 respectively. Prove that the heights reached by them
would be in the ratio of u 2: u 2 ( Assume upward acceleration is –g and 12 downward acceleration to be +g )

pls help
very urgent

Answer 1

1. Given, initial velocities: u₁ and u₂
2. g=acceleration due to gravity, here it is (-g), as the object is thrown vertically upwards
3. Let Final velocities: v₁ and v₂
4. Now, we know that, 
6. For object 1:
8. Putting v=0
9. ..................(i)
10. Similarly for object 2:
11. ......................(ii)
12. Divide (i) by (ii)
14. Therefore,
16. Hence Proved
